科学家借助阻断神经生长的抑制剂新抗体,刺激切断的大鼠脊索,使其神经再生。在3周内新的神经维生素生长11毫米,再生速度是无抗体时的10倍。虽然尚有一些生物化学问题未解决,不能立刻应用于人类,但实验证明科学家已克服了中枢神经系统(CNS)修复的主要障碍之一。上述结果有效地排除了已经消失的概念,即脊椎中枢神经系统不能明显地再生。此外,这些结果加强了到目前为止尚未经动物实验证明的概念,就是受损的CNS神经的命运不仅取决于生长因子,而且取决于促进生长与抑制生长的物质之间微妙的平衡。
Scientists use the new antibody, an inhibitor of nerve growth, to stimulate severed rat spinal cord to regenerate the nerve. In 3 weeks the new vitamin vitamins grow 11 mm, the regeneration rate is 10 times when no antibody. Although some biochemical problems remain unsolved and can not be applied to humans immediately, experiments show that scientists have overcome one of the major obstacles in the repair of the central nervous system (CNS). These results effectively ruled out the concept has disappeared, that is, the central nervous system of the spine can not be significantly regenerated. In addition, these results reinforce the concept that so far has not been demonstrated experimentally in animals, that the fate of damaged CNS nerves depends not only on growth factors but also on the delicate balance between growth-promoting and growth-inhibiting substances.
